Why does the script don't apply to the other duplicated player

Hi, I'm trying to make a multiplayer game so I was trying to test it out by duplicating the player but it doesn't work like the original player I have a ball script it works only with the original player not the duplicated player, sorry guys I'm a beginner programmer

 private GrabController grabScript;
 public GameObject Player
 
 private Animator anim;
 private SpriteRenderer spriteRenderer;
 
 private Rigidbody2D rb2d;
 
 public class Ball : MonoBehaviour
 {
 void Start()
     {
         rb2d = GetComponent<Rigidbody2D>();
 
         grabScript = Player.GetComponent<GrabController>();
         
         spriteRenderer = GetComponent<SpriteRenderer>();
         anim = GetComponent<Animator>();
      }
 
 void Update()
 {
 if(grabScript.isGrabed == true)
 {
         {
             rb2d.gravityScale = 0f;
             spriteRenderer.enabled = false;
             anim.SetBool("stop", true);
             rb2d.constraints = RigidbodyConstraints2D.None;
         }
         else
         {
             rb2d.gravityScale = 1.1f;
             spriteRenderer.enabled = true;
         }
 }
 }
